11-733 40 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=200mm YAG-BBAR 500-1100nm
This is a high-quality achromatic doublet lens from Edmund Optics, catalog number 11-733. The lens is designed with a base shape of a circle and has a diameter of 40 mm. The edge thickness of the lens is 10.09 mm, while the inner and outer radii are 0 mm each. The effective focal length (EFL) of this lens is 200 mm, making it suitable for a wide range of optical applications.
The lens is composed of two types of materials: N-BK7 from Schott and N-SF5 from Schott. This combination helps to correct chromatic aberration, a common issue in optical systems. The lens is coated with YAG-BBAR, which provides excellent transmission in the spectral range of 500-1100 nm.
The geometry of the lens includes a center thickness of 8.5 mm and a center thickness 'a' of 4 mm. The first radius of curvature (r1) is 124.12 mm, and the second radius of curvature (r2) is -87.26 mm. The third radius of curvature (r3) is -253.1 mm.
The lens is available for purchase from the Edmund Optics website, and the link provided is valid and indicates that the lens is in stock. This makes it a readily available option for those in need of a high-performance achromatic doublet lens.
